Vivir como cristianos y pagar como moros: genealogía medieval de la servidumbre morisca en el reino de Valencia
2009
La conversión forzosa de los musulmanes del reino de Valencia, decretada en 1526, no implicó una igualación social entre cristianos «viejos» y «nuevos», ya que se mantuvo la diferencia de estatus que había existido anteriormente. El artículo examina los tres aspectos fundamentales del contenido de dicha diferencia: la intensidad de las rentas soportadas, la imposición de servicios obligatorios y las trabas a la migración interior y exterior; establece sus orígenes en las condiciones de dominación impuestas a la población infiel inmediatamente después de la conquista del siglo XIII, y traza los grandes rasgos de su evolución a lo largo de la Baja Edad Media. Se arguye que esta población estu…
Strategies and Techniques for Powering Wireless Sensor Nodes through Energy Harvesting and Wireless Power Transfer
2019
The continuous development of internet of things (IoT) infrastructure and applications is paving the way for advanced and innovative ideas and solutions, some of which are pushing the limits of state-of-the-art technology. The increasing demand for Wireless Sensor Nodes (WSNs) able to collect and transmit data through wireless communication channels, while often positioned in locations that are difficult to access, is driving research into innovative solutions involving energy harvesting (EH) and wireless power transfer (WPT) to eventually allow battery-free sensor nodes. Due to the pervasiveness of radio frequency (RF) energy, RF EH and WPT are key technologies with the potential to power …
Inhibition Probing on a Cut-Edge Electrode Machined from a Primer-Coated 2024-T3 Alloy
2013
Conventional corrosion protection of 2024-T3 alloys (AA2024T3) in aeronautic structures combines conversion coating with chromate-inhibited primer protected by a top-coat. In some cases this protection can break down after mechanical damage to the paint systems inducing a risk of localized corrosion if the release of inhibitors trapped in the primer does not reach a critical level. There is a need for developing computational models combining the inhibitor release and transport within and from the coating system andthecorrosioninhibitionprocess,toassistinthedesignofnewmultifunctionalcoatingsystems.Theinfluenceonthecorrosioninhibition of various parameters such inhibitor release rate, defect…
Initial Biological Assessment of Upconversion Nanohybrids
2021
Nanoparticles for medical use should be non-cytotoxic and free of bacterial contamination. Upconversion nanoparticles (UCNPs) coated with cucurbit[7]uril (CB[7]) made by combining UCNPs free of oleic acid, here termed bare UCNPs (UCn), and CB[7], i.e., UC@CB[7] nanohybrids, could be used as photoactive inorganic-organic hybrid scaffolds for biological applications. UCNPs, in general, are not considered to be highly toxic materials, but the release of fluorides and lanthanides upon their dissolution may cause cytotoxicity. To identify potential adverse effects of the nanoparticles, dehydrogenase activity of endothelial cells, exposed to various concentrations of the UCNPs, was determined. Da…

Evaluation of the Effects of the Enriched-Organic Diets Composition on European Sea Bass Welfare through a Multi-Parametric Approach
2020
Three groups of European sea bass (Dicentrarchus labrax) were fed for seven months, with either a conventional diet or two different organic diets, which contain organic vegetables and a natural antioxidant compound. The two organic diets differed themselves in terms of raw proteins, fish oil, and lipid contents. Sea bass welfare condition was assessed in relation to these three diets, using 16 different indicators. These were: swimming activity (recovery test, muscle activity), haematological and serological stress indicators (haematocrit, haemoglobin, red-blood-cell count, cortisol, glucose, lactate), aspecific immunity parameter (lysozyme), indicators of exposure to organic contaminants …

On the rearrangement of some Z-arylhydrazones of 3-benzoyl-5-phenylisoxazoles into 2-aryl-4-phenacyl-2H-1,2,3-triazoles: a kinetic study of the subst…
2015
Abstract The rearrangement of eight new Z -arylhydrazones of 3-benzoyl-5-phenylisoxazoles ( 3d – k ) into the relevant 2-aryl-4-phenacyl-2 H -1,2,3-triazoles ( 4d – k ) in dioxane/water solution at different proton concentrations has been quantitatively studied in a wide temperature range (293–333 K). The data collected together with some our previous ones on compounds 3a – c have allowed a deep study of the substituent effects on the course of the rearrangement, thus increasing our knowledge on the Boulton–Katritzky reactions in isoxazole derivatives and on the temperature effects on free energy relationships.
Donner soi-même, donner autrui. Conversion d'adultes et oblation d'enfants en Provence (fin Xe-XIIe siècle)
2010
Taking as its point of departure the case of Provence as documented in the diplomatic sources of Benedictine monasteries and in hagiography, this article demonstrates that the increase in the conversion of adults in the second half of the eleventh century is unrelated to a supposed decline in child oblation. Contrary to the traditional perspective, oblation appears to remain stable and the oblate monk (nutritus) is still the ideal model of monastic perfection as opposed to the converted monk (conversus), an alternative model then offered to the seigniorial aristocracy.
Null alleles of human complement C4. Evidence for pseudogenes at the C4A locus and for gene conversion at the C4B locus
1990
The two genes for the C4A and C4B isotypes of the fourth component of human complement are located in the MHC class III region. Previous studies have demonstrated the unusual expression of C4 genes in the form of aberrant or duplicated haplotypes. Null alleles of C4A or C4B (AQ0 or BQ0) have been defined by the absence of gene products and occur at frequencies of 0.1-0.3. However, only some C4 null alleles are due to gene deletions, the remainder were thought to be nonexpressed genes. We have analyzed the C4 gene structure of 26 individuals lacking either C4A or C4B protein. The DNA of individuals with apparently nonexpressed C4 genes was tested for the presence of C4A- and C4B-specific seq…
